Amp out- If you are using a guitar amp, connect the Plexi-Preamp to the power amp through your amp’s return, doing this bypasses your amp’s preamp. If you are using only a power amp, connect directly to the power amp input.

The Baroni-Lab Plexi gives you that rich Plexi experience in a small affordable package with top-of-the line technology. This is a true to tone sounding Plexi unit that even uses the original voltage requirements. Awesome is the only way to describe this product and the value.
